    摘要: A type 1 system and a type 2 system are classified according to whether carrier aggregation is used. A shared component carrier is used for both a type 1 terminal and a type 2 terminal, whereas a dedicated component carrier is used only for the type 2 terminal. Also, a type 2 base station transmits broadcast information by using a shared component carrier. In this instance, the broadcast information includes the shared broadcast information used for both the type 1 terminal and the type 2 terminal and the dedicated broadcast information only for the type 2 terminal. Also, the type 2 base station indicates component carriers that are used by the type 2 terminal, by using a semi-static component carrier indicator or a dynamic component carrier indicator.

    摘要: Provided are a data transmission method in a communication system and a relay performing the same. The data transmission method in a communication system includes receiving, at a relay, an uplink buffer status report (BSR) of a terminal from the terminal, including the uplink BSR of the terminal received by the relay in an uplink BSR to be transmitted from the relay to a base station to generate a combined uplink BSR, and transmitting the combined uplink BSR to the base station even before the relay receives data stored in an uplink buffer of the terminal from the terminal. Accordingly, it is possible to reduce the transmission delay of the communication system including a relay.

    摘要: Provided is a technology adopting multiple transmit antennas in a radio communication system. In a mobile communication system of a signal carrier frequency division multiple access (SC-FDMA) scheme, it is possible to transmit data using the multiple transmit antennas, while maintaining a peak to average power ratio (PAPR) to be low. Also, it is possible to provide a new transmit diversity transmission even in a general radio communication system including an orthogonal frequency division multiple access (OFDMA), a code division multiple access (CDMA) scheme, and the like.
